Abstract
A process for capturing or concentrating microorganisms for detection or assay comprises (a) providing a particulate concentration agent that comprises gamma-FeO(OH); (b) providing a fluid sample comprising at least one microorganism strain; and (c) contacting the concentration agent with the sample such that at least a portion of the concentration agent is dispersed in the sample and at least a portion of the at least one microorganism strain is bound to or captured by the concentration agent.
Claims25
A process comprising (a) providing a particulate concentration agent that comprises gamma-FeO(OH);
- (b) providing a fluid sample comprising at least one microorganism strain;
- and (c) contacting said concentration agent with said sample such that at least a portion of said concentration agent is dispersed in said sample and at least a portion of said at least one microorganism strain is bound to or captured by said concentration agent.
A process comprising (a) providing a microparticulate concentration agent that comprises gamma-FeO(OH);
- (b) providing a fluid sample comprising at least one strain of microorganism selected from bacteria, yeasts, viruses, bacterial endospores, and combinations thereof;
- and (c) mixing said concentration agent and said sample such that at least a portion of said concentration agent is dispersed in said sample and at least a portion of said at least one strain of microorganism is bound to or captured by said concentration agent.
